Hello, I just did a full scan, and two files could not be scanned. ??? *BOOTC: Error: No more data is available (259)
*MBR0 Error: The maximum number of secrets that may be stored in a single system has been excedded (1281)
Generally there is nothing to be concerned with, files that can’t be scanned are just that, not necessarily suspect or infected.
It is just avast open and notifying you of files that couldn’t be scanned, many other AVs don’t even tell you. So for most ignorance is bliss and I don’t know if that is the way avast should go and simply not report them as it causes more concern that it really deserves.
